My invention relates to the positioning of beari k 9 onshafts, pins andthe like, particularly to the positioning of the inner bearing membersof roller bearings.

The invention has for its principal object to provide a positioningmeans that is easily positioner ant removed and that permts adjustmentof the bearings.

T he invention. consists principally in a bearing positioning meansincluding a twopiece ring mounted in an annular groove on the shaft onwhich the bearing is mounted and provided with a tongue engaging alongitudinal groove in said shaft to prevent rotc tion of said two-pieceretaining ring. The invention further consists in the bearingpositioning means and in the parts and combinations and ar .gements ofparts hereinafter described and claimed.

in the accompanying drawing, which forms part of this specification andwherein like reference characters indicate like parts wherever theyoccur,

Fig. 4 is an end View of the construction shown in Fig. 3., and

Fig. 5 is a sectional view through a trolley wheel construction one ofwhose bearings is provided with a removable abutment similar to thepositioning means illustrated in Fig. 1.

In F 1 is illustrated a steering gear contact pin 1 mounted in atransverse opening through a rocker shaft arm Said pin 1 has formedthereon conical raceway at for one series of bearing rollers 5 and hasmounted thereon a separate cone or inner bearing member 6 for the otherseries of rollers The outer raceways for said rollers 5 are formed inthe bore 2 of said arm 3.

My invention is concerned with the secur- 50 ing of said separate innerbearing member 1932. Serial NO. 6121584.

6 on said pin 1. Said pin 1 is provided with a longitudinal groove 7extending from the outer end to a point somewhat inwardly of the end ofthe inner bearing member 5. Abutting against said inner bearing member 6is a washer 8 having a tongue 9 projecting into said groove '4', wherebyrotation of said washer 8 is prevented. T he pin 1 is provided near itsouter end with an annular groove ll) shallower than the longitudinalgroove 7. Mounted in said annular groove 10 are halfring members 11, oneof which is provided with a tongue 12 extending into said longitudinalgroove 7. In order to hold said halfring members 11 on said pin 1, saidwasher 8 is provided with a plurality of prongs 13 that may be bent overthe outer periphery of said half-ring members 11. Preferably, the face14 of the washer in contact with the inner bearing member is hardened,as by cyanizing.

The washer 8 and ring members 11 hold the inner bearing member 6 inposition. Adjustment of said inner bearing member 6 is obtained eitherby using a washer 8 0r rings 11 of different thickness or by insertingshims 15, as shown in Fig. 1.

In the construction shown in Figs. 3 and 1-, the washer 8 is eliminated,the two halfring members 1166 being held in place by an annular spring16 disposed in a peripheral groove 17 in said ring members 11. The innerperiphery of each ring member 11a is free from projecting portions and akey 20 fitting in the longitudinal groove 7 of the pin 1 and in a grooveor keyway 21 in one half-ring member 116; prevents said assembled ringmember from rotating on said pin. Said key 20 has an enlarged headportion 22 forming shoulders 23 that prevent the key from slipping outof said longitudinal groove 7 Adjustment of this hearing is obtainedeither by using shims or by using ring members of different thickness.

Fig. 5 illustrates a trolley wheel construc tion including a trolleywheel rotatably mounted upon a stub shaft 31 held in a suitablesupporting arm 32. At one end of said shaft 31 is an annular groove 33in which are mounted half-ring members 11?; held in place by means of aWasher 86 having prongs 13b bent over the periphery of said ring members11?). Said washer 8b constitutes an abutment for a cone or inner bearingmember 6?) on which are mounted rollers 5 that cooperate with a can 34mounted in the bore of said trolley n neol 30. A second cup 35 mountedin said trolley wheel bore cooperates with a second series of rollers 5mounted on a second cone 36 or inner bearing member. Said second cone 36is held in place by means of a suitable ring 37. Closures 38 areprovided for the ends of the trolley wheels. In this construction, thehalf-rings 11?) are an abutment or positioning device, not an adjustingdevice.

My invention is easily applied and removed and the construction shown inFig. 5 eliminates the necessity of an expensive machining operation toform an abutment shoulder on a shaft. Rings of desired size may easilybe made and by selecting rings of proper thickness, adjusting shims maybe dispensed with, although the device also has the advantage offacilitating the mounting of adjusting shims in position.

What I claim is:

A bearing positioning means comprising a shaft having a seat for aninner bearing member, said shaft having a longitudinal groove extendingoutwardly from said seat for said inner bearing member and having anannular groove communicating with said longitudinal groove, half-ringsmounted in said annular groove, one of said half-rings having a tongueprojecting into said longitudinal groove, and a washer interposedbetween said half-ring members and said seat for said inner bearingmember, said washer having prongs engaging the outer periphery of saidhalf-ring members to hold them in place and also having a tongueextending into said longitudinal groove.
